An engineer notes that some areas of a floor fail when using the Location Readiness Tool in Cisco WCS. What criteria must be met for a point to be considered location ready?

one AP in each quadrant, with three less than 70 feet away

one AP in three quadrants, with two less than 70 feet away

one AP in each quadrant, with two less than 70 feet away

one AP in three quadrants, with one less than 70 feet away

Answer: A

You have been contacted by a medium-sized hospitality company that has 50 hotels. They would like to upgrade their existing WLAN in each hotel to 802.11n. While performing the site surveys for each hotel, what are the issues that you need to take into consideration when determining the locations for each AP?

Selecting AP locations where power is already available

Selecting APs that can be hidden in ceiling panels to provide a secure and clean aesthetic look

Selecting locations that are easily accessed so maintenance and upgrades can be performed quickly

Selecting locations that make visual assessment of the AP operation easy

Answer: B

When using WCS 7.0 to calibrate a floor, is it more important to collect 50 or more distinct locations or to collect 150 measurements?

150 measurements are more important than the locations because the information gathered is more granular.

Collecting 50 or more distinct locations is more important because this provides a wider coverage across the floor being calibrated.

Depending on the size of the floor 50 distinct locations and 150 measurements may provide divergent information that requires more data collection.

When calibrating a floor 50 or more distinct locations will yield 150 measurements because multiple measurements are collected at each distinct location.

Answer: D

Which three types of infrastructure issues need to be verified prior to performing a wireless site survey? (Choose three.)

MDF and IDF closet locations and if the cable that runs from each closet can reach the proposed AP locations.

Available riser capacity for additional backbone cable connections

VLAN and IP address deployment strategy

Status of QoS deployed

Electrical capacity for each MDF and IDF

HVAC capacity for each MDF and IDF

Locations of application servers

Answer: A,C,D

Question No: 125

Which statement best describes an outdoor RF point-to-point antenna deployment?

Both antennas must be vertically polarized.

Both antennas must be horizontally polarized.

There should be a 90 degree difference between antennas for best results.

There should be a 180 degree difference between antennas for best results.

It does not matter so long as both antennas have matching polarization.

Answer: E

On which two items will data be collected when an engineer is conducting a passive survey? (Choose two.)

RF interference

rate shifting data rates

roaming

rouges

encryption

Answer: A,D

Question No: 127

In which two ways does the type of industry vertical change the way you prepare to perform a wireless site survey? (Choose two.)

In most cases the specific industry vertical impact is not unique and information used to prepare for a site survey can be reused from one vertical to another.

The first step in preparing for a site survey for a specific industry vertical is to review the individual industry standards for a WLAN deployment to ensure compliance with all known standards.

Each industry vertical has its own specific challenges that need to be considered prior to completion of the WLAN site survey.

Prior to performing a site survey for a customer, their specific industry vertical has very little impact on site survey process. Only post-survey design is impacted by the industry vertical.

Answer: B,C

Question No: 128

What are two advantages of conducting an active survey versus a passive survey when verifying RF coverage? (Choose two.)

verifies roaming

verifies signal level

verifies packet loss

verifies SNR

verifies interferers

Answer: A,C

Question No: 129

An engineer is performing a data collection to validate wireless coverage. At what two locations should a linear point collection be performed? (Choose two.)

office cubicles

private offices

auditorium

warehouse

conference rooms

Answer: C,D

Question No: 130

During the site survey kick-off meeting with your customer, they ask why you need to verify the existing network infrastructure. Which two reasons do you give them? (Choose two.)

You need to verify the make, model, and software versions of all the equipment that will connect to the WLAN components in order to ensure compatibility.

You need to verify that the equipment the WLAN components will connect to has sufficient memory capacity to support the additional WLAN connections.

You need to verify that there are sufficient switch ports to support the new WLAN connections.

You need to verify that the switches the WLAN components will connect to can supply 802.3af inline power, and that they have sufficient ports to support all the new WLAN devices.

Depending on the type of APs that are planned for, the deployment may require different types of PoE to be supplied by the LAB switches.
